Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall structure for a dry method, and more particularly to a studless partition wall structure for forming a wall surface by an extruded plate.

[0002]

2. Description of the Related Art As a partition wall for a dry construction method in a building or a work, a lightweight steel frame having a frame structure in which a building face material (board material) such as gypsum board or calcium silicate plate is attached to a stud of a steel stud. The partition wall is widely used for practical purposes. In this type of partition wall, the steel studs are aligned at predetermined intervals along the wall core, and the upper and lower ends of the steel studs are fixed to the upper runner and the floor runner, respectively. The board material forming the wall is attached to the runner and steel stud framework by screws, staples, adhesives, or the like.

In recent years, an abnormal noise of a partition wall, which is generated when a strong wind blows, has been regarded as a problem in middle and high-rise buildings. This kind of abnormal noise is generally called a rubbing sound, and various measures to solve the problem of rubbing sound have been proposed so far.

The rubbing noise is believed to be primarily due to building behavior or story displacement. For example, when a building vibrates for a long period during strong winds and interlayer displacement between floors occurs, an unintended forcing force or external force acts on the partition wall, and stress acts on the constituent members of the partition wall. Due to such a stress in the partition wall, the respective constituent members of the partition wall tend to be displaced relative to each other, and as a result, the members in frictional contact generate rubbing noise such as squeak noise.

In order to prevent such rubbing noise, as disclosed in Japanese Utility Model Laid-Open No. 6-14310, a low friction sliding material such as PP tape or Teflon (registered trademark) tape is used for a stud, a runner and Insert it in the contact part of the board,
Alternatively, as disclosed in Japanese Examined Patent Publication No. 4-47742, a measure for connecting an upper structure such as an upper floor slab or a beam to an upper runner via a special metal fitting for reducing rubbing noise is proposed, These measures have already been put to practical use.

[0006]

The generation of rubbing noise has hitherto been considered to be a problem peculiar to a light iron partition wall provided with light iron studs. Therefore, in a partition wall without studless structure (also called non-stud structure) that does not include light iron studs, for example, in a partition wall in which a ribbed board with vertical ribs or vertical ribs or an extruded plate is installed, It is considered that the problem of scratching noise does not occur, and in this type of partition wall, the occurrence of scratching noise is not regarded as a particular problem, and measures against it have not been considered.

However, it has been confirmed by the present inventors that, in the partition wall of the studless type in which the extruded plate is built between the upper and lower runners, a rubbing noise is generated similarly to the light iron partition wall. Even in this type of partition wall, the necessity of taking measures against scraping noise has been recognized.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a studless partition wall structure in which a wall surface is formed by an extruded plate, and a scratch noise is reliably generated by a simple construction. It is to prevent the occurrence.

[0009]

In order to achieve the above object, the present invention comprises an upper runner and a floor runner, and an extrusion plate vertically installed between the runners. In the partition wall structure of the dry method and the studless type, the molding plate has a rib portion protruding into the partition wall on the back surface, and a groove into which the side edge portion of the upper runner can be inserted is formed at the upper end portion of the rib portion. A low-friction member having a side edge portion of the upper runner, a pair of adhered portions that are interposed between the inner surface of the groove, and a connecting band that interconnects the adhered portions on both sides. The partition wall structure is characterized in that the adhered portion slidably contacts the side edge portion and the inner side surface to prevent generation of rubbing noise due to rubbing of the side edge portion and the inner side surface.

According to the above configuration of the present invention, the low-friction member is inserted into the upper groove of the extruded plate to prevent contact between the inner surface of the groove and the edge of the upper runner, so that the extruded plate and the upper runner are contacted with each other. Prevents the generation of scraping noise due to contact with In the partition wall having the above structure, the generation of rubbing noise is substantially completely eliminated by such rubbing noise prevention means. The low-friction members can be attached to both edges of the upper runner immediately before installing the extruded plate, so take measures to prevent rubbing noise quickly and easily without affecting other steps of partition wall construction. be able to. Moreover, since the low-friction member can be stably supplied to the construction site as a molded part or a processed part that can be mass-produced at low cost, it does not substantially affect the construction cost of the partition wall.

[0011]

According to a preferred embodiment of the present invention, the low friction member is an integrally molded component of synthetic resin, rubber or elastomer. According to another embodiment of the present invention, the low friction member is formed by bending a synthetic resin, rubber or elastomer plate body.

According to a further preferred embodiment of the present invention, the low friction member has a width substantially the same as the width of the rib. According to another preferred embodiment of the present invention, the low friction member is an elongated member extending along the upper runner.

Preferably, a refractory material or sound insulation material is inserted between the upper end surface of the extruded plate and the upper floor structure.
The refractory material improves the fire resistance of the partition wall,
It functions as a cushioning material that absorbs the relative displacement between the extruded plate and the building structure. Further, the sound insulating material prevents abnormal noise generated inside the partition wall from leaking into the room.
